Thanks for the query to H.C.M. Forum.
As you stated that you are having cyst
, so the pain may be due to cyst.
Next query is that in belly button there may be cyst?
However it is not possible to say any thing at this because without physical examination.
This may be a cyst or may be umbilical hernia
Consult a surgeon and get his opinion as physical examination will reveal the exact nature of disease.
will help in cyst diagnosis.
Gynaecologist will tell you about the cyst course .
